For several years I was a loyal T-Mobile customer. I loved their service. I paid one simple price per month, which included unlimited data, unlimited texting, built-in tethering, and a generous amount of voice calling. In addition to that, their service allowed for travelling overseas with your cell phone at no extra cost; carrying your cell phone out of the country was simply covered by your plan.
There was only one fatal problem which I ran into that made me have to change carriers: I had no cell phone coverage in my home office. This was a deal-breaker for me. I have two-factor authentication (2FA) turned on for work and most of the websites where 2FA is available, so having no coverage in my office meant that I had to login initially for work or a website on my computer, then walk outside and stand in my backyard until I received the call or text message to complete the authentication process. This was obviously unacceptable, so I begrudgingly realized that I would have to change carriers; which was really too bad, since T-Mobile worked great for me when I lived in Seattle.
So my wife and I started shopping around between the different carriers; e.g. Verizon, Sprint, AT&T, etc. Eventually we decided to go with Verizon since their coverage seemed to be the best. However, once the honeymoon period of having cell phone coverage in my office had passed, I realized the shocking revelation of just how expensive Verizon could be.
As I mentioned earlier, T-Mobile was a flat fee which was reasonably-priced and provided lots of great features at a low cost which easily beat the competition.
Verizon, on the other hand, wants to charge you for everything. They have found dozens of ways to exceed the airline industry by nickle-and-diming its customers for everything on their phones. You want Caller ID? You'll have to pay for that. You want to use your phone overseas for a few weeks? Prepare to pay hundreds of dollars. You want to use data services on your phone? Prepare to pay through the nose. You want to use tethering with your laptop/tablet? That'll be another $50 or so for two phones. Pretty much any feature on your phone comes at an additional cost.
In addition to the exorbitant fees, for some reason which I have never been able to ascertain, using Verizon for the same data services which I used on T-Mobile required around four times the amount of data. Before I switched carriers, I saw that I was using about 1GB of data per month for the apps that I use; e.g. email, FB, streaming, etc. So when I switched to Verizon, I went with a 2GB plan just to be safe. But I used that up almost immediately, and I quickly upgraded to a 4GB plan. But that was also used up pretty quickly, and I changed to an 8GB plan. Of course, each data service upgrade increased my costs yet again, so cha-ching, cha-ching, cha-ching... The next thing I know I'm paying Verizon two or three times what I paid for T-Mobile services, with less features.
Oh, and one more thing: on our first-month bill, my wife and I had a huge data usage the first day. This might seem normal because of downloading apps to a new phone and such, but when I looked at the per-hour breakdown on my bill of data usage, the largest part of the data usage happened before I was actually given the phone. After my wife and I had picked out our phones, the sales guy at the Verizon store said that it was going to take a little while to get things set up, so my wife and I agreed to head out to lunch and run some other errands and return to pick up our phones later that afternoon. What I am presuming happened was the sales rep upgraded our phones with new versions of the operating systems after my wife and I left the store, which seems like a good idea in principle, but I didn't think that I should have to pay for hundreds of megabytes of data usage before I actually owned the phone; Verizon should have covered the cost of upgrading the phones with the latest bits just because that's good customer service. And with that in mind, I tried fighting those charges with Verizon, but - of course - I lost that battle.
I have only had Verizon for one year now, but that has been more than enough time for me to come to the following inescapable conclusion: I HATE VERIZON.
